Any body out there in the UK have some spare, good condition saddles going for a 1986 Goldie?

Mine have gotten worn with string grooves over 31 years and this effects the sustain as it is a little choked especially on the three unwound.
I've tried gentle filing to see if i can improve them but it's not really helping.

I'm looking for this era as I want to keep as original as possible. I've some spare Gotoh ones but they are just a tad wider.
